Hi! Roedy Green wrote: > in windows you spawn > w32tm.exe /resync In a corporate network you should have (at least) 2 servers that run ntpd getting the time signals from multiple outside sources. You should ask for permission to use these sources. Then close the ntp port in the firewall for everyone except these servers. All your other systems should get the time from your own time servers. On Unix/Linux boxes install ntpd and have it point to your corporate time servers. Sync your Windows domain controllers with your corporate ntp servers, all computers in the domain will get their time from there. Your windows systems that are not part of a domain should get their time from your ntp servers. To automate this I use a batch file to set/change the registry entries. Here the content: w32tm /register w32tm /config /manualpeerlist:"Your corporate servers" reg add HKLM\System\CurrentControlSet\Services\W32Time\Parameters /v "Period" /t REG_DWORD /d 0 /f reg add HKLM\System\CurrentControlSet\Services\W32Time\Config /v "MaxNegPhaseCorrection" /t REG_DWORD /d 4294967295 /f reg add HKLM\System\CurrentControlSet\Services\W32Time\Config /v "MaxPosPhaseCorrection" /t REG_DWORD /d 4294967295 /f Setting the maximum correction to infinity makes sure that a system with a bad CMOS battery is still synced.
